I have not measured the depth of the p-spring cover/cup on the Gran Sport RD, but it is from 53-59 as it has the adjuster for cable tension. No original pulley wheels.
The Titan handlebars have "55" stamped on the botton, so manufactured in 1955?
Hubs are Normandy with Maillard QRs. Weinmann concave on rear, don't know what the front is.
Pedals are Union, I put a thread gauge there but couldn't really tell if 1.25mm or 20tpi. Most likely imperial, they were in tight..
No original bolts for the chain rings. Correct ones are M7 and of course the ones I got were M6...
I have a theory on how the drive side dropout got bend. The bolt in the drive side fender eyelet was facing head in and my guess is that it was first mounted head out and the bolt stuck so far in, so close to the freewheel, that it caught the chain, locked up and made the axle push down on the dropout.
Meinn Gott, those are 630 wheels on the Monark. I have now four sets of 630 that I do nothing with.
